Ceramic roller bearings
SI3N4 ceramic bearing rollers: advantage: 1. resistance to wear: SI3N4 is more wearable than steel. 2. corrosion resistance: better than ZRO2 ceramics, and can be used under high-temperature water-vapour condition 3. heat-resistant: to 1000 °C 4. self-lubricating. 5. long life time.
